Final answer:
Trichomoniasis is treated with an oral antibiotic, and treating the sexual partner at the same time is crucial to prevent reinfection. Abstinence from sexual intercourse is recommended until both partners have been cleared by a physician after treatment.
Step-by-step explanation:
The treatment (tx) for trichomoniasis, an infection caused by Trichomonas vaginalis, typically involves a single dose of an oral antibiotic. It is recommended to treat the sexual partner simultaneously because of the high risk of reinfection. Engaging in sexual intercourse should be avoided until both partners have completed their treatment and have been examined by a healthcare provider. While azithromycin or doxycycline is often used to treat Trichomonas vaginalis, other alternatives like erythromycin, levofloxacin, and ofloxacin are available if necessary.
Importantly, simultaneous treatment of partners is crucial to prevent the passing of the infection back and forth, which could occur if only one partner is treated. Abstinence from sexual activity is advisable until a follow-up with a physician confirms that the infection has been successfully treated for both individuals.
